SPECIFICATION forming part of Letters Patent No. 645,262, dated March 13, 1900. Application tied January 13,1399. sentira. 702,073. (No maar.)

To all whom t may concern:

Be it known that I, KINSEY JONES, a citizen of the United States, residing at Janesville, in the county of Rock and State of Wisconsin, have invented a new and useful Sleigh-Knee,

-of which the following is a specification.

and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a sleigh-knee constructed in accordance with this invention. tudinal sectional View. Fig. 3 is a transverse sectional View. Fig. 4 is a detail perspective view of the runner-plate. Fig. 5 is a similar view of the knee detached.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a runner-plate provided at opposite sides with longitudinal flanges 2, which are perforated for the reception of a transverse bolt 3, which secures the plate to a runner 4. The runner-plate is provided at its upper face with a concave seat 5, formed in an enlargement and'receiving the rounded bottom portion o of a knee 7, provided with a horizontal top portion 8, which is bolted to a beam 9. The ends of the enlargement in which the seat 5 is formed are provided with vertical perforations 9 and form sockets or thimbles for vertical bolts or rods 10, which are connected at their upper ends with the rave 11. The concave seat is provided with a longitudinal rib or tongue 12, and the rounded bottom portion of the knee is provided with a corresponding groove 13 to receive the rib or tongue, whereby the parts are Fig. 2 is a longi-l interlocked and supported against lateral strain.

, The rods or bolts, which are vertical, have their upper ends threaded, and their lower ends, which are provided with heads, are countersunkin the inner face of the runnerplate and are interposed between the same and the upper face of the runner. The upper threaded ends of the rods or bolts receive nuts l5, which engage the rave, and when the latter is firmly bolted at its ends 16 to the runner the parts form a truss and provide a y firm construction. v

The knee is provided at its front and rear faces with parallel vertical anges 17, form- .ing vertical ways or grooves forthe rods or `bolts and extending from the top to the bottom of the knee to afford a support on the bolts or rods the entire length ofv the knee, whereby the latter is enabled to oscillate considerably without weakening the construction to permit the runner to yield to the configuration of the surface.

By separating the walls of the knee from each other, as shown inFigs. 2 and 3, alight hollow casting is formed' which possesses the requisite amount of strength for supporting the load upon the sleigh, and by extending the end walls above the tops of the side walls they embrace the beam of the sleigh, and thereby add to the strength of the structure.

The invention has the following advantages The device, which is simple and comparatively inexpensive in construction, is light, strong, and durable. opposite sides of the knee proper provide a continuous bearing for the rods, so that the knee may be permitted to oscillate considerably and still be supported by the rods or bolts; also, byproviding the-concave seat in the runnerplate bosses or thimbles are formed for supporting and strengthening the lower ends of the rods or bolts, and the latterdo not have to be extended into the runner.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
